General Mach Discussion / tuning motor issue
« on: January 26, 2009, 10:33:50 PM »
Hello.

I am running a 3 axis hobbycnc product with mach3. 2 of the motors I can tune very easy and moving it fractions of an inch is flawless.

When I go to tune my table Y axis stepper no matter what I do I get missed steps at start and at fraction of an inch turns motors sound like they are arcing. I turn the accel and velocity up and it sounds a lot better but missed steps get a lot worse.

When I do get the motors to stop losing steps it is so slow and sounds like its running quarter speed.

I have read just about every post here and did the corrections I found including the step pulse and direction but couldnt find much more that helps.

Any other suggestions?

Thanks

Louis

General Mach Discussion / cannot get motors to turn on
« on: January 23, 2009, 01:42:06 PM »
Hello.

First time startup on this build. I used a hobbycncpro board and all tested perfect for voltage/amp readouts before I wired it into the 3 axis 425 oz steppers. I setup mach3 config and ran a test program to see if the motors would turn on. I can see mach three running but the motors are acting like they have no power to them at all.

I have read everything I could find but all configs look correct. Could someone tell by my xml file if my configs are ok?

Thanks

Louis
